After her mother passed away from breast cancer, Chelsea Campbell, only a junior in high school, was called upon to take care of her mentally and physically handicapped sister, Alexis.

Virginia native and six-time Tough Mudder finisher Heather Ferguson is much more than a World’s Toughest Mudder. She’s mother to the World’s Toughest Baby. So what exactly constitutes “tough” for a baby? How about running 1,600 miles… before being born. Yes, we thought she had some explaining to do too--that’s why we asked Heather to tell her story of her daughter Zoey, aka World’s Toughest Baby (WTB), in her own words.
